Change the load_image so that it returns success or failure of the
command (using CMD_RET_SUCCESS or CMD_RET_FAILURE).

This way, hush scripts can optionally load different files depending
upon the system configuration.

A simple example:

if afs load ${kernel_name} ${kernel_addr}; then echo loaded; else echo \
not loaded; fi
